Variation of Counterion Binding in Micelles of Cetyltrimethylammonium Hydroxide

Article abstract of DOI:10.1021/j100242a003

Reaction of N-methyl-4-cyanopyridinium fluoroborate (1) with OH^- in aqueous micelles of cetyltrimethylammonium hydroxide (CTAOH) occurs wholly in the aqueous pseudophase.Comparison of the rate constants in CTAOH and NaOH allows estimation of the concentrations of free and micellar bound OH^-.The values of α, the fractional ionization of the micelles, decrease with increasing concentration of OH^-, in agreement with evidence from reactions of substrates bound to micelles of CTAOH.
